Did they change wolves reaction to revolvers?

[Jolan]

Did they change how wolves react to revolvers?  I'm playing on Stalker and wolves have previously a) charged when aiming a revolver and b) been scared off by a revolver shot.  Now they a) charge as soon as I pull the the revolver, no aiming, just have it out and b) don't react in fear to a shot, probably because they're charging.  Also, all of the wolves on the map (6 of them near the broken railroad shed) kept charging, even the ones up at the top of the slope.  I'm trying to decide if this is a "feature" or a "bug".  They were acting a lot like the wolves did when they first introduced the scent mechanic.
